The following discussion provides various examples of semiconductordevices and methods of manufacturing semiconductor devices. Suchexamples are non-limiting, and the scope of the appended claims shouldnot be limited to the particular examples disclosed. In the followingdiscussion, the terms “example” and “e.g.” are non-limiting.

The figures illustrate the general manner of construction, anddescriptions and details of well-known features and techniques may beomitted to avoid unnecessarily obscuring the present disclosure. Inaddition, elements in the drawing figures are not necessarily drawn toscale. For example, the dimensions of some of the elements in thefigures may be exaggerated relative to other elements to help improveunderstanding of the examples discussed in the present disclosure. Thesame reference numerals in different figures denote the same elements.

The term “or” means any one or more of the items in the list joined by“or”. As an example, “x or y” means any element of the three-element set{(x), (y), (x, y)}. As another example, “x, y, or z” means any elementof the seven-element set {(x), (y), (z), (x, y), (x, z), z), (x, y, z)}.

The terms “comprises,” “comprising,” “includes,” or “including,” are“open ended” terms and specify the presence of stated features, but donot preclude the presence or addition of one or more other features. Theterms “first,” “second,” etc. may be used herein to describe variouselements, and these elements should not be limited by these terms. Theseterms are only used to distinguish one element from another. Thus, forexample, a first element discussed in this disclosure could be termed asecond element without departing from the teachings of the presentdisclosure.

Unless specified otherwise, the term “coupled” may be used to describetwo elements directly contacting each other or describe two elementsindirectly connected by one or more other elements. For example, ifelement A is coupled to element B, then element A can be directlycontacting element B or indirectly connected to element B by anintervening element C. Similarly, the terms “over” or “on” may be usedto describe two elements directly contacting each other or describe twoelements indirectly connected by one or more other elements.

In the example shown in FIG. 1 , semiconductor device 10 cancomprise substrate 11, base component 15, electronic component 16, lidstructure 17, seal 18, and external connector 19. Seal 18 can be betweenthe top side of substrate 11 and a bottom side of lid structure 17.External connector 19 can connect with vertical interconnect 172 in lidstructure 17 to connect with lid connector 173. Vertical interconnect172 can extend to a stop surface of lid structure 17 and can beelectrically coupled with conductive structure 111 of substrate 11, forexample via lid connector 173. Lid structure 17 can comprise lid cover17A and lid sidewall 17B defining lid cavity 171, where lid cover 17Acovers a top side of electronic component 16, and lid sidewall 17Bbounds lateral sides of electronic component 16. Electronic component 16can be in lid cavity 171 and can be over a top side of substrate 11.Substrate 11 can comprise conductive structure 111, dielectric structure112, and substrate terminal 1111. In some examples, first componentterminal 151 can electrically connect base component 15 and substrate11. In some examples, second component terminal 161 can electricallyconnect electronic component 16 with substrate 11 to electricallyconnect to conductive structure 111.

Substrate 11, lid structure 17 and external connectors 19 can bereferred to as semiconductor package or package and can protectelectronic components 16. In some examples, semiconductor package canprovide electrical connection between external components and basecomponent 15 or electronic components 16.

FIGS. 2A to 2H show cross-sectional views of an example method formanufacturing an example semiconductor device 10. FIG. 2A shows across-sectional view at an early stage of the method of manufacture. Inthe example shown in FIG. 2A, substrate 11 can be provided and cancomprise top side 11 a and bottom side 11 b opposite to top side 11 a,conductive structure 111, and dielectric structure 112. Base component15 can be provided and can be at bottom side 11 b of substrate 11. WhileFIG. 2A shows two base components 15 coupled to bottom side 11 b of twosubstrates 11, multiple base components 15 and substrates 11 can bearranged to be spaced apart from one another in a row-wise orcolumn-wise direction.

In some examples, substrate 11 can comprise or be referred to asmulti-layered printed circuit board (PCB), a pre-formed substrate,coreless substrate, a Re-Distribution Layer (RDL) substrate, aninterposer, or a lead frame. In some examples, substrate 11 can have athickness in the range from approximately 5 micrometers (μm) toapproximately 250 μm.

In some examples, substrate 11 can be a redistribution layer (“RDL”)substrate. RDL substrates can comprise one or more conductiveredistribution layers and one or more dielectric layers that (a) can beformed layer by layer over an electronic device to which the RDLsubstrate is to be electrically coupled, or (b) can be formed layer bylayer over a carrier that can be entirely removed or at least partiallyremoved after the electronic device and the RDL substrate are coupledtogether. RDL substrates can be manufactured layer by layer as awafer-level substrate on a round wafer in a wafer-level process, or as apanel-level substrate on a rectangular or square panel carrier in apanel-level process. RDL substrates can be formed in an additive buildupprocess that can include one or more dielectric layers alternatinglystacked with one or more conductive layers that define respectiveconductive redistribution patterns or traces configured to collectively(a) fan-out electrical traces outside the footprint of the electronicdevice, or (b) fan-in electrical traces within the footprint of theelectronic device. The conductive patterns can be formed using a platingprocess such as, for example, an electroplating process or anelectroless plating process. The conductive patterns can comprise anelectrically conductive material such as, for example, copper or otherplateable metal. The locations of the conductive patterns can be madeusing a photo-patterning process such as, for example, aphotolithography process and a photoresist material to form aphotolithographic mask. The dielectric layers of the RDL substrate canbe patterned with a photo-patterning process, which can include aphotolithographic mask through which light is exposed to photo-patterndesired features such as vias in the dielectric layers. The dielectriclayers can be made from photo-definable organic dielectric materialssuch as, for example, polyimide (PI), benzocyclobutene (BCB), orpolybenzoxazole (PBO). Such dielectric materials can be spun-on orotherwise coated in liquid form, rather than attached as a pre-formedfilm. To permit proper formation of desired photo-defined features, suchphoto-definable dielectric materials can omit structural reinforcers orcan be filler-free, without strands, weaves, or other particles, thatcould interfere with the light from the photo-patterning process. Insome examples, such filler-free characteristics of filler-freedielectric materials can permit a reduction of the thickness of theresulting dielectric layer. Although the photo-definable dielectricmaterials described above can be organic materials, in other examplesthe dielectric materials of the RDL substrates can comprise one or moreinorganic dielectric layers. Some examples of one or more inorganicdielectric layers can comprise silicon nitride (Si₃N₄), silicon oxide(SiO₂), or silicon oxynitride (SiON). The one or more inorganicdielectric layers can be formed by growing the inorganic dielectriclayers using an oxidation or nitridization process instead usingphoto-defined organic dielectric materials. Such inorganic dielectriclayers can be filler-fee, without strands, weaves, or other dissimilarinorganic particles. In some examples, the RDL substrates can omit apermanent core structure or carrier such as, for example, a dielectricmaterial comprising bismaleimide triazine (BT) or FR4 and these types ofRDL substrates can be referred to as a coreless substrate. Othersubstrates in this disclosure can also comprise an RDL substrate.

In some examples, substrate 11 can be a pre-formed substrate. Thepre-formed substrate can be manufactured prior to attachment to anelectronic device and can comprise dielectric layers between respectiveconductive layers. The conductive layers can comprise copper and can beformed using an electroplating process. The dielectric layers can berelatively thicker non-photo-definable layers that can be attached as apre-formed film rather than as a liquid and can include a resin withfillers such as strands, weaves, or other inorganic particles forrigidity or structural support. Since the dielectric layers arenon-photo-definable, features such as vias or openings can be formed byusing a drill or laser. In some examples, the dielectric layers cancomprise a prepreg material or Ajinomoto Buildup Film (ABF). Thepre-formed substrate can include a permanent core structure or carriersuch as, for example, a dielectric material comprising bismaleimidetriazine (BT) or FR4, and dielectric and conductive layers can be formedon the permanent core structure. In other examples, the pre-formedsubstrate can be a coreless substrate which omits the permanent corestructure, and the dielectric and conductive layers can be formed on asacrificial carrier that is removed after formation of the dielectricand conductive layers and before attachment to the electronic device.The pre-formed substrate can rereferred to as a printed circuit board(PCB) or a laminate substrate. Such pre-formed substrate can be formedthrough a semi-additive or modified-semi-additive process. Othersubstrates in this disclosure can also comprise a pre-formed substrate.

A portion of conductive structure 111 can be exposed at thetop or bottom of dielectric structure 112 to be electrically connectedto base component 15, electronic components 16, or external connectors19. In some examples, conductive structure 111 can comprise copper,iron, nickel, gold, silver, palladium, or tin.
